A Novel Study on Non-invasive Assessment of Renal Osteodystrophy among Iranian Hemodialysis Patients
Background: Renal osteodystrophy (ROD) is a common bone and mineral metabolism disorder in patients with end-stage renal disease (ESRD). This study aimed to determinate the frequency of the subtypes of ROD and evaluate the diagnostic value of biochemical as the well as radiographic markers for the diagnosis of ROD among hemodialysis patients in Golestan province of Iran. Materials and Methods...
Background: Osteoblastoma is one of the rarest primary benign bone tumors which accounts for 1% of all bone neoplasms and 3.5% of benign bone tumors, with the potential for local invasion and recurrence. Osteoblastoma is not homogeneous. Differences in histological details have led to the division of these lesions into subtypes. The histologic features in most cases are distinctive, there are v...

Osteoporosis is a disease of high prevalence with increased bone loss. It has potential public health threat and that the health authorities had taken several measures for its control. In recent years, considerable attention has been given to physiopathology of osteoporosis. Oxidative stress has been proved to be involved in bone resorption. Oxidative stress occurs when balance between o...
In the rare hereditary bone disorder of osteopetrosis, reduced bone resorption function leads to both the development of densely sclerotic fragile bones and progressive obliteration of the marrow spaces and cranial foramina. Marrow obliteration, typically associated with extramedullary hemopoiesis and hepatosplenomegaly, results in anemia and thrombocytopenia and nerve entrapment accounts for p...
